Each divert rule goes to a different natd, each of which is attached to a different outgoing interface. > > -- > -- > Alex Pilosov | http://www.acecape.com/dsl > CTO - Acecape, Inc. | AceDSL:The best ADSL in Bell Atlantic area > 325 W 38 St. Suite 1005 | (Stealth Marketing Works! :) > New York, NY 10018 | > > To Unsubscribe: send mail to majordomo@FreeBSD.org > with "unsubscribe freebsd-net" in the body of the message -- __--_|\ Julian Elischer / \ julian@elischer.org ( OZ ) World tour 2000-2001 ---> X_.---._/ v To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-net" in the body of the message
